Post by Joe Burton, Chief Technology Officer, Unified CommunicationsAs I read my colleague Alan Cohen’s excellent Halloween post the other day, I was reminded of the many conversations I’ve had with our best customers concerning how to manage who has access to what type of information -- the notion of policy management across an organization. Virtually all our customers want the business acceleration of Unified Communications, collaboration, and web 2.0. In fact, we would all like to use these capabilities to give us what we want, how we want it, on any device, RIGHT NOW.Unfortunately, policy and compliance concerns often prevent widespread deployment of some of the more advanced capabilities that are now available. For Enterprise 2.0 to take off, we need to bring the web 2.0 capabilities of ad hoc, virtual, shared, flexible, distributed, dynamic collaboration inside the enterprise but without loss of security, privacy, and system integrity. For some time now, Cisco has been working on ways to express policy in a standard form external to applications. We believe web-based policy management as a strategic tier in the enterprise IT stack and a way to facilitate our customers’ transition to Enterprise 2.0 technologies. By expressing policy in a network service that is external to individual applications, we can uniformly apply it to all applications, communications, and content within an enterprise, and in the future, across enterprise boundaries.With that in mind, I was delighted that on November 1st we announced our intention to bring Securent into Cisco. Securent’s standards-based, distributed architecture allows enterprises to administer, enforce, and audit access to data, communications, and applications in heterogeneous IT application environments based on the context of who is accessing the information.I’ve known Rajiv Gupta and Sekhar Sarukkai for a long time. I’m delighted to welcome them and the rest of Securent to Cisco. Together, I’m confident we will do great things for our customers and the future of Enterprise 2.0.
